Whilst the Cabinet War Rooms at St James housed the government over WW2 there was a secondary bunker under development 40 ft under sleepy Neasden near Wembley. Codenamed Paddock, this bombproof shelter was strong enough to survive a direct hit had the Battle of Britain been lost – accommodating the entire war cabinet and 200 staff.
The bunker was sold to Network Stadium Housing Association in 1997 who have spent a modest amount on it to stop it flooding. It is in a pretty raw state – really don’t expect any fancy interactive exhibits, you’ll only find the most delicately formed stalactites. It is open a couple of days a year and the next day is looming on the horizon. Worth noting, if you do miss this it is always open over September’s Open House.
